    1.

    Shaft

    Alignment

    and Loading

    A.

    Guard

    against

    unusual

    stresses

    and

    overloads

    by

    accurately

    aligning

    the various

    drive

    members

    (motor,

    speed

    reducer,

    coupling,

    sprocket.

    sheave.

    gear,

    etc.).

    B.

    Flexible

    couplings

    are

    recomrnended

    if

    a

    prime

    mover

    shaft

    is to

    be directly

    connected

    to the

    inpui

    shaft

    or if the

    output

    shaft is

    direcfly

    connected

    to

    the

    driven

    shaft.

    Note:

    Flexible

    couplings

    hav,e

    a

    limited

    capacity

    for

    misalignment.

    Ensure

    that

    shaft

    alignments

    are within

    the

    limits

    recommended

    by

    the

    coupling manufacturer

    at installation.

    Even

    slight

    misalignments

    in

    a rigid

    mounting

    system

    may

    bring

    about

    binding,

    large

    vibration

    forces,

    or

    excessive

    overhung

    loading;

    each in

    itself

    promoting

    premature

    bearing,

    shaft,

    or

    speed

    failure.

    Do

    not

    excessively

    force

    couplings

    or

    other

    connection

    devices

    onto

    either

    input

    or

    output

    shafts;

    the result

    may

    be

    permanent

    bearing

    damage.

    Ensure

    all

    shaft

    keys

    are

    captive

    and

    secured

    before

    operation.

    C. A common

    base plate

    supporling the motor

    and

    reducer

    will

    help

    preserve

    the

    original

    alrgnment

    between

    the

    reducer

    and

    the

    motor

    shaft. lf

    a

    structural

    steel

    base

    is

    used,

    the

    plate

    should

    be

    at

    least

    equal

    in thickness

    to

    the

    diameter

    of the

    base

    plated

    fastening

    bolts.

    ln

    addition,

    the

    structure

    suppofting

    the

    base

    plate

    must

    be

    sufficienily

    rigid

    that

    it

    prevents

    excessive

    flexing

    during

    normal

    operation.

    D.

    Vibration

    tends

    to loosen

    fasteners

    even

    if they,

    are

    initially

    tight.

    After

    the

    first

    week

    or two

    of

    operation,

    all fasteners

    within

    the

    drive

    assembly

    should

    be retightened.

    Doweling

    the

    motor

    and

    speed

    reducer

    to

    the

    base

    plate

    will

    help

    maintain

    alignment.

    E.

    Excessive

    thrust or

    overhung loads on

    the

    input

    or

    output

    shafts

    of

    a

    uses

    a

    pillow

    block

    or

    flange

    bp-anng

    on

    the

    opposite side of

    the

    conveyor from the

    speed

    reducer as

    a

    support

    bearing.

    This

    provides

    tnree bearings

    for alignment

    purposes.

    lt

    is

    difficult

    to

    maintain and

    align

    a

    system

    with

    a

    rigidly

    mounted

    bearing

    close

    to

    a

    rigidly mounted

    speed

    reducer.

    lt

    is

    extremely

    important

    to

    "custom

    align"

    and

    "custom

    shim" all

    components

    prior

    to tightening

    mounting

    bolts

    when using a

    rigid

    mounting

    approach.

    This minimizes

    misalignment

    that is caused

    by excessive

    loads.

    Select

    an appropriate

    key

    when using

    a bushing

    in

    the

    output

    bore of any

    hollow

    Face Motor

    Mounting

    Procedures

    A. C Face/Quill

    Motor

    Mounting

    1.

    Check

    the

    motor and

    reducer mounting

    registers

    for

    nicks that could

    interfere

    with

    assembly;

    remove

    if necessary.

    2. Remove

    protective plastic

    from

    the reducer input

    shaft.

    The bore

    has been coated

    with an anti-seize

    compound.

    3.

    Align

    the

    motor shaft and

    key

    with

    keyway in

    bore

    and slide

    motor up

    input adaptor.

    4. Position

    the motor conduit box as

    desired.

    5. Secure

    the motor

    to the reducer using the

    supplied

    fasteners.

    Ensure

    proper

    motor

    seating

    before

    tightening

    the fasteners. lf

    the

    motor

    does

    not readily seat

    itself. check for axial movement

    of

    the moior

    shaft

    key

    as ihis

    can

    cause

    interference. Staking

    the

    keyrvay

    adjacent

    io

    ihe

    motor key will help

    preveni

    axial movement of the

    key

    during

    the

    mounting procedure. Draw down

    evenly on the

    fasteners

    to avoid

    bending the

    motor

    shaft

    and tighten to 200 lbf-in maximum.

    B.

    G

    Face Coupling

    Motor

    Mounting

    1.

    Check

    the

    motor and reducer mounting

    registers

    for

    nicks

    thai could

    intedere with

    assembly.

    Remove if necessary.

    2.

    When

    assembling

    the motor and coupling,

    the

    coupling

    halves

    should

    be evenly spaced

    on each shaft

    to

    obtain

    proper

    engagement.

    The

    following describes a method for doing

    this:

    3.

    Determine the

    assembled shaft

    clearance

    by

    measuring the distance from the C Face

    to the

    reducer shaft end

    and subtracting

    the motor

    shaft

    length. Mount and secure

    the

    motor shaft

    side of

    the coupling

    such

    that the

    spider-end

    of

    the coupling

    is located

    one half of

    the

    clearance

    distance beyond

    the

    motor shaft.

    Mount

    the

    reducer coupling

    half and

    coupling spider

    onto

    the reducer

    shaft

    in its approximate

    Sealed

    vs. Vented Speed

    Reducer

    Operation

    All SE Encore series speed

    redrc"rs

    are designed

    to

    operate sealed or

    vented. Deciding whether a speed

    reducer should operate

    sealed or vented requires an

    understanding of

    the application, the environment, the

    operation

    of

    radial

    shaft seals,

    and a review of the

    fundamentals

    of

    thermodynamics that

    govern

    the

    temperature

    and

    pressure

    relationship in the speed

    reducer.

    Any significant increase in

    pressure

    in a sealed speed

    reducer decreases

    the

    operational service life of the

    radial

    lip

    seals. A

    pressure

    change

    of

    only

    5

    psi

    may

    reduce

    the

    seal

    life

    by as

    much

    as one third.

    There

    are

    two impoftant

    phenomena

    that cause

    an

    increase in

    the

    internal

    pressure

    of

    a sealed speed reducer.

    First,

    the

    change of

    internal

    pressure

    during operation

    is

    proporlional

    to the change of

    internal temperature

    that

    occurs during normal operation.

    The relationship

    follows

    the combined

    gas

    law expressed

    as

    Secondly,

    radial

    lip seals

    can

    ingest

    or

    "pump"

    air

    into

    a speed

    reducer

    regardless

    of

    whether

    it

    is

    operating

    sealed

    or

    vented.

    While

    the

    rate

    of

    ingestion

    is

    highly

    variable

    and

    dependant

    on

    running

    and

    speed'

    under

    continuous

    conditions

    effect

    of

    to

    the

    total

    significant.

    caused

    by

    both

    and

    thermal

    expansion.

    ln some

    applications,

    the

    duty

    cycle

    of

    the

    speed

    is

    intermittent,

    the

    and

    the

    modest'

    While

    sealing

    reducer

    during

    operation

    subsequently

    increases

    the

    pressure

    in

    these

    applications,

    the

    increase

    may

    be

    of equilibrium

    results

    in

    a corresponding

    change

    in

    both

    oil volume

    and internal

    Moreover,

    the

    thermal

    expansion

    of

    the

    lubricant

    in the

    can

    have

    a considerable

    effect

    on the

    pressure,

    and volume

    relaiionship.

    The influence of

    the

    depends

    on

    the

    percent

    Correctly

    operating

    radial

    shaft

    lip

    seals

    are

    dynamic

    and

    require

    the

    presence

    of a microscopically

    thin

    film

    of

    lubricant

    directly

    under

    the

    sealing

    lip.

    The

    seal

    lip

    imposes

    shear

    forces

    on the

    film

    as the

    shaft

    rotates

    beneath

    it. This

    creates

    a seal

    "pumping

    action',

    that

    circulates

    the

    lubricant

    residing

    closest

    to

    the

    seal

    back

    inside

    the

    speed

    reducer

    and

    away

    from

    the

    external

    environment.

    The

    pumping

    action

    of the

    seal

    prevents

    the

    lubricant

    from

    seeping

    out

    and is

    necessary

    for

    proper

    operation.

    Unfortunately,

    a

    correcfly

    functioning

    radial shaft

    seal

    also causes

    an

    unintended

    and unavoidable

    side

    effect.

    Tests

    confirm

    that

    microscopic

    air

    bubbles

    and

    contaminants

    from

    the

    external

    environment

    are

    entrained

    in

    the lubricant.

    The

    actively

    pumping

    seal

    sweeps

    them

    inward

    with

    the

    induced

    lubricant

    flow

    and

    once inside,

    they

    escape

    into

    the

    speed

    reducer.

    With

    continuous

    operation,

    the

    air

    bubbles

    accumulate

    inside

    the

    reducer

    cavity.

    The

    seal

    is

    acting

    as

    an air

    pump,

    causing

    air ingestion

    that

    increases

    the

    internal

    pressure

    of

    a sealed speed

    reducer.

    Winsmith,s

    extensive

    testing

    has

    verified

    that

    the

    increased

    internal

    pressure

    of the

    speed

    reducer

    and

    the rate

    of

    pressurization

    are

    dependent

    on

    many

    variables

    including

    operating

    time,

    linear

    velocity

    of

    the

    shaft

    under

    seal,

    temperature,

    seal

    material,

    and

    i

    ln

    summary,

    a

    significantly

    large

    percentage

    of

    sealed

    speed

    reducers

    develop

    an

    internal pressure

    of 5

    psi

    or

    more

    when

    operated

    on a continuous

    duty

    cycle.

    This

    phenomenon can

    lndicates

    that

    when

    The impact

    of

    increasing

    temperature

    and

    pressure

    in a

    sealed

    speed

    reducer

    on

    the service

    life of an

    NBR seal

    has

    been assessed

    by

    numerous

    seal

    manufacturers.

    While

    the results

    of these

    tests

    vary depending

    on

    variables

    such

    as

    a

    change

    in

    pressure

    as

    small

    as

    5

    psi

    can

    reduce

    the

    expected

    seal

    service life by

    one

    third.

    This

    is because

    a

    positive

    internal

    pressure

    differential

    in a

    speed

    reducer

    causes

    the shaft

    lip

    seals

    to

    exerl

    a

    higher

    radial

    force

    on

    the

    shaft.

    Under

    dynamic

    conditions,

    this

    force

    increases

    the

    lip seal

    contact

    area

    on

    the shaft,

    increasing

    the

    friction,

    and

    thereby

    creating

    a

    correspondingly

    higher

    temperature

    between

    the

    shaft

    and

    the

    lip

    seal.

    This

    increase

    is directly

    proportional

    to

    the

    amount

    of

    radial

    force

    on

    the seal

    and

    to

    the

    speed

    of

    the shaft

    at the

    seal

    interjace

    and

    causes

    6

    Applications

    Determine

    When

    Sealing

    a Speed

    Reducer

    is Preferred

    to

    Venting

    As covered

    in the

    preceding

    discussion,

    sealing

    a

    reducer can

    increase

    the

    internal

    pressure

    which

    results

    in decreased

    seal

    service

    life.

    This

    is especially

    prevalent

    when operating

    under

    continuous

    duty

    conditions.

    However,

    there

    are

    cedain

    applications

    where

    the speed

    reducer

    duty

    cycle

    is highly

    intermittent,

    and

    run

    times are

    short

    with

    light average

    duty

    loads.

    Testing

    and

    field

    experience

    indicate

    that

    small

    internal

    pressure

    increases

    (1

    -

    2

    psi)

    have

    a

    minimal

    effect

    on

    the

    seal

    service

    life'

    Another

    application

    dependent

    situation

    where

    sealed

    reducer

    operation

    is

    preferred

    occurs

    when

    the external

    air environment

    is extremely

    contaminated

    with

    material

    that,

    if drawn

    into the

    reducer

    through

    a

    vent,

    can

    rapidly reduce seal, bearing, or worm gear life.

    ln

    these

    applications,

    the

    increased

    pressure

    resulting

    from

    operating

    a sealed

    reducer

    can

    still

    have

    a significantly

    negative

    effect

    on seal

    life

    and,

    in

    these

    cases,

    require

    more

    frequent

    seal

    replacement.

    However,

    the

    reducer

    life

    may be

    lengthened

    by operating

    sealed

    rather

    than

    operating

    with

    an

    open

    vent

    in these

    types

    of harsh

    environments.

    Further,

    the rinachine

    builder

    or

    equipment

    operator

    might

    (jetermine

    that

    the

    convenience

    of operating

    a,'sealed

    speed

    reducer

    outweighs

    the negative

    result

    of

    reduced

    seal

    service

    life.

    decision

    only

    affects the

    service

    life of

    the speed

    wear

    components.

    ln conclusion,

    there

    are

    three fundamental

    factors

    that

    govern

    the

    speed

    reducer

    seal/vent

    decision.

    First,

    as

    the temperature increases in

    a

    sealed

    reducer,

    so

    will

    the

    pressure.

    Second,

    the radial

    shaft

    seals

    are

    designed

    to

    "pump"

    lubricant

    back

    into

    the speed

    reducer.

    This

    pumping

    action

    also

    causes

    an

    ingestion

    of

    air thai

    increases

    the internal

    pressure.

    Any

    increase

    of

    pressure

    causes

    decreased

    dynamic

    radial

    seal

    life.

    Venting

    is

    the

    most

    cost

    effective

    method of

    eliminating

    the

    pressure.

    Finally,

    when

    extreme

    environmental

    conditions

    cause

    component

    or seal

    wear

    in

    excess

    of

    that caused

    by an

    increased

    internal

    pressure,

    the best

    likely alternative.

    However,

    under these

    conditions,

    Winsmith's

    '100

    years

    of

    experience,

    we have

    found

    that

    the

    actual

    service

    life

    of many

    of our

    reducers

    exceeds

    25.000

    hours

    by several

    multiples.

    Under

    severe

    conditions (rapid

    temperature

    changes,

    moist,

    dirty.

    or corrosive

    environments)

    it may

    be

    necessary

    to

    change

    the

    oil

    at

    intervals

    of

    1-3

    months.

    Periodic

    examination

    of

    oil

    samples

    taken

    from

    the

    reducer

    will

    help

    establish

    the

    appropriate

    interval.

    The

    oil change

    procedure

    for

    all

    SE Encore

    speed

    Grease

    Fittings

    Some

    speed

    reducer

    models are equipped

    with

    grease

    fittings

    to

    lubricate bearings

    that

    are

    not adequately

    lubricated by

    the oil splash.

    These

    fittings

    must

    be lubricated

    every 3-6

    months

    depending

    on

    the

    operaiing conditions. Winsmith

    uses

    Mobilith

    SHC

    220

    or equivalent

    (NLGI

    #2). Caution

    should

    be

    used

    when

    greasing

    because

    excessive

    grease

    may

    reduce

    the

    pedormance

    of

    the lubricant

    inside

    the speed

    reducer.

    7.

    Low

    lnput

    Speeds

    (Under

    1160 RPM)

    When input

    speeds

    are

    less

    than

    1160 RPM,

    grease

    fittings

    will be

    required

    to

    lubricate

    any

    bearings

    not

    parlially

    covered

    by

    the normal

    oil

    condition

    exists

    and

    are

    without

    8.

    Oil

    Temperature

    Speed

    reducers

    in normal operation

    can

    generate

    temperatures

    of

    up

    to

    200 degrees

    F depending

    on

    the

    type of

    the

    reducer and

    the

    severrty

    of

    the application

    (loading,

    duration of

    service,

    ambient

    temperatures).

    Excessive

    oil temperatures

    may be

    the result

    of one

    or

    more of

    the following factors:

    A. Overloads

    Overloads

    may be due

    to the

    original

    model

    being

    too small

    for the application.

    Overloads

    can

    also

    occur

    if the

    speed

    reducer is

    properly

    sized

    for the

    application

    and higher

    than

    anticipated

    loads

    are

    experienced.

    Always check

    the reducer

    rating

    when increasing driven

    loads or

    when increasing

    the

    horsepower rating of

    the

    motor or other

    prime

    mover.

    B. Overfilling or

    Underfilling

    lf a speed reducer

    is

    overfilled

    with oil,

    the

    energy

    used

    in

    churning

    the

    excessive oil can

    result in

    overheating.

    lf overfilling occurs, shut

    down the

    drive,

    remove the oil level

    plug,

    and

    allow oil

    to drain

    from

    the level

    hole until

    it

    stops.

    Reinstall

    the level

    plug

    and

    restarl

    the drive.

    lf

    the

    speed

    reducer

    is under

    filled,

    the

    resultant

    friction

    can

    cause overheating

    and

    possible

    damage.

    lf this occurs,

    the

    reducer should

    be

    disassembled

    and

    inspected

    for

    excessive

    wear.

    10

    Replace damaged

    components,

    reassemble

    the

    reducer, and fill

    with lubricant

    to the

    appropriate

    levelfill hole.

    \/

    C.

    Inadequate Cooling

    ln order

    to

    dissipate

    internally

    generated

    heat,

    the

    speed reducer must be installed

    in

    such

    a

    way

    that air can circulate

    freely.

    Tightly confined

    areas,

    (inside

    cabinets,

    etc.) should be avoided.

    lf

    this

    is

    not

    possible.

    use

    a separate blower

    to

    provide

    forced air

    cooling.

    9. O¡l

    Seals

    and

    Wear ComPonents

    Various

    normal

    wear

    components

    such as

    seals,

    bearings

    and

    gears

    may

    need more

    frequent

    replacement

    in

    severe

    applications.

    Gear reducer

    shaft

    lip seals

    are all

    subject

    to

    wear.

    Experience

    indicates

    that

    their

    useful

    life

    is

    extremely

    variable,

    and based

    primarily

    on

    the operating

    temperature.

    Other

    operating

    factors

    that

    influence

    seal

    life are

    high input shaft

    speeds

    and environmental

    factors

    such as air-born

    abrasjve

    padiculates.

    lnspecting

    the

    gear

    reducer regularly

    and replacing

    the

    shaft

    seals at the

    first sign thqt

    they are beyond

    their

    useful

    life is

    the

    only

    methodof

    ensuring

    no lubricant

    leakage.

    This might be as

    frequently as

    2

    years

    or less

    in some applications;

    in others

    it

    can

    be as

    long as

    10

    years

    or

    more.

    Winsmith

    uses

    high

    quality

    oil

    seals

    and

    precision

    ground

    shafts. However,

    it is

    possible

    that

    damage

    during

    shipment

    or

    installation

    can cause oil

    seal

    leakage. When replacing a shaft

    oil

    seal,

    the following

    suggestions will help ensure

    leak free operation

    and

    long seal life:

    A.

    When installing a new seal, cover

    the

    keyway

    and

    any other

    shaft

    surface discontinuities

    with smooth

    tape

    to

    protect

    the

    seal

    lip from being damaged.

    B.

    Use

    a sealant between

    the

    OD of

    the

    seal

    and the

    lD of

    the

    bore into which

    the

    seal

    is being

    installed.

    The

    seal bore should also

    be

    free of any

    burrs,

    nicks,

    or scratches.

    C.

    Be

    sure

    that the

    seal

    is not cocked

    in the seal bore.

    The outer face of the seal should

    be

    flush with the

    outer surface of

    the

    reducer.
